Polyurethane red iron oxide anti-rust primer (2K) for steel structures and long-term anti-corrosion.
For steel structures anti-rust priming.
Mixing ratio 4:1; pot life 3 h.
Compatible with polyurethane and acrylic polyurethane topcoats.
Overview
Two-component anti-rust primer with fast drying and low-temperature applicability.
Features include very good adhesion, anti-rust performance, and resistance to oil and water.
